Service Description
Elbie ransomware decryption and recovery, Hyper Virtual Machine (VHDX) file decryption and recovery, VHDX virtual disk file decryption and recovery.
This case involves professional recovery of Hyper-V virtual machine data after a ransomware attack that encrypted critical VHDX files.
Client & Data Information
- Client Name: Confidential
- Data Type: Hyper Virtual Machine (VHDX)
- Data Capacity: 7 TB
Incident Summary
The server was infected with ransomware, which encrypted all files and added the .Elbie extension. As a result, the entire Hyper Virtual Machine environment became inaccessible.
The problem required recovery of the VHDX files in the Hyper Virtual Machine, which were fully encrypted by the ransomware. Due to the large data volume and the importance of the virtual machines, standard decryption or copy-based recovery methods were not suitable.
Technical Challenge
Elbie ransomware encrypts not only file content but also affects the internal structure of large virtual disk files. In this case:
- All VHDX virtual disks were encrypted
- Hyper-V could not start virtual machines normally
- The total data volume reached 7 TB, increasing recovery complexity
- Any incorrect operation could result in permanent data loss
Professional tools and precise repair techniques were required to ensure safe recovery.
Recovery Solution
The repair results were achieved using the SQL110vhdxfix repair tool to process VHDX backup files encrypted by the .Elbie virus.
Instead of relying on unsafe decryption attempts, the recovery focused on repairing and reconstructing the internal VHDX structure. This method preserved the original data layout and ensured compatibility with the Hyper-V environment.
Recovery Results
- Recovery Rate: 100%
- Recovered Files: All Hyper-V VHDX virtual disk files
- System Status: Hyper-V can be used directly upon startup
- Data Integrity: Fully preserved
All recovered virtual machines were able to run normally without additional configuration or data reconstruction.
